The Church of Ireland Parish / Civil Parish / Church Mapping cross-reference data was compiled using Lewis Topographical Directory of 1837 and the Ecclesiastical Directory in Thom's 1848 Directory as primary reference sources and matching Parishes listed in these to Civil Parishes on the 1851 Townland Database and 1st Edition OSI Maps c1837-1842.

This is a beta version of the system, so may exhibit some issues, and further data will be loaded as each Diocese is processed (at present 14 Diocese with parts of 16 counties. See list below)

Three options are currently available for searching this data on this page :

Search by Civil Parish. This option allows selection of a County, Barony (optional) and Civil parish, and uses this data to check if this Civil Parish has been cross-linked to one or more Church of Ireland Parishes. A link provides further details of the Parish (see next option). Unlinked Civil parishes include a list of nearby Churches and Parishes based on a coordinate search.

Search by CofI parish. This option allow selection of a Church of Ireland Diocese and Parish, and shows linked civil parish data and details of Churches noted, alternate names for the parish, along with a map showing locations on a map of Churches and Chapels associated with the parish. Links are also provided to show the locations of the churches on the Historic OSI maps, and on current Google maps. A list of nearby Parishes is also included.

Extended Parish Search. This search accepts one or more keywords, and searches multiple fields on all linked parishes for potential matches. Fields checked include Parish Name, and any alternate names, Church details, Parish Notes, names of linked Civil parishes and names and notes for any mapped churches. The search allows several keywords, with at least three characters required, and all of which must be included to result in a match.

Notes : spelling varies a great deal in all the place names used, particularly in Lewis, and there were also some changes in land divisions after Lewis’ Directory was published - e.g. some Baronies combined and some civil parishes also appear to have had minor border changes over this timeframe.
